public class GPoint extends GObject implements HasParents<GObject>, DecomposeWhenDrawn<Point>
GPoint is a class that represents a single point in 3D space.

Unlike other GObjects who's pivot has to be calculated to be it's geometric centre, a GPoint's pivot is just its position.

a Thing stores GPoints separately as they form the core of any transformation irrespective of whether it's part of some other geometry. This means all transformations need to be point based and applied to the GPoint.

A GPoint is also stored within SceneManager.points for redundancy.

      Specified by:
      getParents in interface HasParents<GObject>

      parent - The parent object to remove.

    • copy

      public void copy(CopyProperties props) throws InvalidCopyException
      Description copied from interface: CanCopy
      Copies the properties of this object based on the provided CopyProperties. The implementation should handle how the copying is performed, potentially creating a new instance or modifying an existing one.

      Overrides:
      copy in class GObject
      Parameters:
      props - The properties defining how the copy operation should be performed.
      Throws:
